Okay. Found where I mentioned this earlier in thread.

I don't pay taxes all year. I'm still at work staring at my check to be mailed tomorrow, I'm sweatin and ****tin and hyperventilating and cramping and hallucinating and in denial. Might be the (irs inflicted) blood coming out of my rear, I dunno.

So, go by what I said in the below quotes when I was halfway normal:

Merc uses the 2" throttle bore TBI's that flow about 640cfm stock and complete. So....maybe mid 700's ?

I would check with Edelbrock for the block off plate. Their TBI to MPI conversion set up removes the injector pods and uses a plate. Maybe available seperate ?

Thanks buddy. I didn't even think about looking back a few pages. It's been a VERY long last few weeks and my brain isn't working at full speed right now.

...should have just left them on there when you were mocking them up! By the way, I'm hoping to fire the boat up in a week or 2. Just waiting for the water to clear up.

I should have. We can make more though. Let me know if you need anything.
It going to be a while if your lake looks anything like ours. It has rained here probably 12 of the last 14 days. I tried to run a boat last week and the lake looked like a lumber yard. I've never seen that much wood in the lake before.

So I put about 12 hrs on the new fuel injection setup last week at havasu. The boat has NEVER ran, started or idled as good as it does now. All of my quirky idle problems are gone. I truly believe this upgrade is worth every penny for a 575 owner. It now runs like it should have from the factory. Thanks Eddie

That's great to hear Joe. I've been wanting to call you to see how it ran at Havasu. I'm very glad to hear that it works well. Now I just need to build a few dozen more. lol
Let me know if you need anything else.

That's great news - at least we have alternatives now for the 575's.

What did you do for a tune? Have you checked where you stand AFR wise? I see this set up in my near future

Great to hear, the stock 575 setup definitely leaves a lot to be desired.....but it gives me an excuse to rev my engines at the dock
